Process for preparing low molecular weight polytetrafluoroethylene

Vinyl ethers having a carboxyl group in a form of salt are stable and is usable as materials for fluorine-containing copolymers. The vinyl ethers can provide stable monomer compositions by mixing with vinyl ethers having a free carboxyl group when the former vinyl ethers are present in an amount of not less than 1% by mole of the latter vinyl ethers. The fluorine-containing copolymer prepared by copolymerizing fluoroolefins with the vinyl ethers are useful as aqueous coatings particularly electro dip coatings.
